NASA launches earth-monitoring Landsat 9 Satellite in California

On Monday, US space agency NASA cleared the launch of Landsat 9. It is a powerful Earth-observing satellite containing four tiny satellites. Being a joint mission between NASA and US Geological Survey (USGS), Landsat 9 will monitor Earth's land and coastal regions that began with the first Landsat satellite in 1972.

Following the tradition, Landsat 9 satellite will take the orbital track of Landsat 7, which will be decommissioned.

Deb Haaland, who is the Interior Secretary, mentioned that the Landsat program provides “a rich form of data” that helps people’s everyday lives and is vital in dealing with climate change.

Teams from NASA and USGS will collectively work with a predecessor, Landsat 8, to extend a nearly 50-year record of land and coastal region observations. This data will be used to study differential patterns and evolvement of earth from 1972, the first Landsat.

Haaland further added that they are in the thick of the climate crisis right now. They see that every day drought, and wildfires. Hurricane Ida devastated parts of the South and went all the way up to New England. Images like the ones that Landsat 9 will bring back, will help them to guide and direct as in how to approach climate change.

The scientists will be working to make sure that with the data at hand they can make the best decisions possible so that people have water into the future and we all continue to grow our food.

The four satellites have been mounted on a ring-shaped frame, called the ESPA (Evolved Expendable Launch Vehicle Secondary Payload Adapter). This ESPA will be attached inside the top section of the rocket, mainly CubeSats. When the rocket will reach its second stage, called the Centaur, it will drop to a lower orbit and send the CubeSats on their way.

From there CuPID will study the boundaries of Earth's magnetic field, to see how energy from the Sun can break through our planet's magnetic shield, while the CUTE will train its telescope on planets outside our solar system to study how quickly their atmospheres are escaping.

It is significant for this launch to be successful since this breakthrough technology could make future satellites easier to use and repair, with fewer moving parts to tear down.

PM Modi Stresses Climate Finance and Technology at COP28 for Global South's Ambitions

 During the COP28 Presidency's session on Transforming Climate Finance, Prime Minister Narendra Modi emphasized the crucial role of climate finance and technology in realizing the aspirations of countries in the Global South, including India. Despite their limited contribution to climate change, these nations bear immense consequences, and PM Modi highlighted their unwavering commitment to climate action, despite resource constraints. Addressing the gathering, PM Modi stated, "We all know that countries in the Global South, including India, have played a lesser role in climate change. But the impact of climate change on them is immense. Despite a lack of resources, these countries are committed to climate action." He expressed the expectation of Global South nations for robust support from developed countries to combat climate change, considering the natural and justified need for assistance. PM Modi welcomed the decision to operationalize the Loss and Damage Fund, adopte

Bangladesh Military Expresses Discontent Over Chinese Weapons; Reports 'Sub-Standard' and Faulty Parts

  Bangladesh, a traditional buyer of Chinese military equipment, has raised grievances with Beijing regarding the delivery of defective components and technical malfunctions in its imported military hardware. This issue is not unique to Bangladesh, as other nations like Myanmar have also encountered problems with Chinese fighter jets, according to an ET report. Experts in the Chinese defense industry argue that Beijing lacks the expertise to manufacture highly sophisticated military hardware and is not yet considered a top-tier producer of modern defense equipment. They claim that much of China's weapon systems are based on outdated technology copied from the West. Developing countries often opt for Chinese weapons due to their lower cost compared to similar systems from Western countries. China sells arms through state-run export organizations like the Aviation Industry Corporation of China (AVIC), NORINCO, and CVIC. Sources familiar with the matter told ET that the Bangladesh mil

North Korea Celebrates 'New Era of a Space Power' after Satellite Launch

  In a significant development, North Korea recently celebrated what it termed a 'new era of a space power' following the successful launch of a satellite. The reclusive nation's space endeavors have long been a source of international concern and scrutiny, raising questions about its technological capabilities and intentions. This latest achievement has reignited debates and speculation about North Korea's space ambitions. The satellite launch, conducted by North Korea's space agency, comes amid a backdrop of geopolitical tensions and global attention on the Korean Peninsula. The state media hailed the event as a major milestone, highlighting the successful deployment of the satellite into orbit. However, it is important to note that the international community remains skeptical, with concerns over the dual-use nature of space technology that could potentially be applied to ballistic missile systems. North Korea's pursuit of space capabilities has been a conten
